Detailed explanation-1: -The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as -helices and -strands.
Detailed explanation-2: -Which of the following is directly responsible for the shape of an enzyme/protein? The amino acid sequence of the protein and the properties of the amino acids that make up the protein.
Detailed explanation-3: -The shape of a protein is solely determined by the amino acid sequence in the polypeptide chain.
Detailed explanation-4: -Like words in a sentence, the DNA sequence of a gene determines the amino acid sequence for the protein it encodes. In the protein-coding region of a gene, the DNA sequence is interpreted in groups of three nucleotide bases, called codons.
Detailed explanation-5: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.
